检测心电信号QRS波, 检测准确率大于99%，数据库为MIT-BIH 心律失常数据库。(The algorithm can detect the qrs waves automaticlly.)

BP网络的MATLAB实现，用BP网络完成函数的逼近，具体见里面的README(BP Network MATLAB, BP network to be completed function approximation, the specific see inside the README)

瑞利散射的MATLAB仿真代码，来自汪利宏生物成像技术那本著作(Rayleigh scattering of the MATLAB simulation code, WANG Li-hong bio-imaging technology from that book)

这是个手指指纹识别的源代码 ,也是从网络上下载的(This is a fingerprints identification of source code, as well as downloaded from the Internet)

使用阈值法对脉搏信号的峰值进行提取，并且通过提取信号的峰值求脉搏信号的周期，并且简单判断脉搏信号的峰值是否可用。(Useing Threshold to extrack the peak of the pulse signal extraction, and determine the peak of the pulse signal whether is not available.)

本MATLAB代码主要用于EEG脑电信号预处理和单次提取(Single extraction of EEG EEG signal)

可以用FFT频谱对脑电信号进行提取。我们可以利用提取出的各个波段脑电信号，来诊断一些脑部疾病或者对大脑组织的电活动及大脑的功能状态进行分析。 1.将实验测得的脑电数据文件转换为文本文件(已经过50Hz陷波)， 获得在Matlab 平台上可直接使用的脑电信号数据，即0661.txt。 2.在Matlab中导入数据，并提取Fp1通道的脑电信号，通过FFT变换对α，β，θ，δ波段进行提取，并做FFT逆变换变到时域。 3.计算各个波段的功率谱。(FFT spectrum can be extracted on EEG. We can use the extracted EEG each band to diagnose some brain disorders or brain tissue on the brain' s electrical activity and functional status were analyzed. One would experimentally measured EEG data file into a text file (has been 50Hz notch), obtained in Matlab platform can be used directly EEG data, that 0661.txt. (2) import data in Matlab and extract Fp1 channel EEG by FFT transform α, β, θ, δ bands were extracted, and do FFT inverse transform variable to the time domain. 3 calculate the power spectrum of each band.)
